   # Bug Description
   
   The helm chart provides no ordering guarantees for restarting components.  
This makes upgrading a cluster that is controlled with Helm extremely difficult 
since components should be upgraded/restarted in a specific order.  Not having 
control restarts all components at once which renders a fully-operational 
cluster in a bad error state.
   
   To mitigate this, users can change the `updateStrategy` to `OnDelete` so 
they can have full control over which components are restarted and when.  
Zookeeper and Bookkeeper already have such a helm value, but Brokers and 
Proxies do not.  To make the functionality consistent, Brokers and Proxies 
should also be able to control this value via the Helm chart.
   
   ## Expected Behavior
   A user should be able to set `updateStrategy` for Brokers, Proxies (in 
addition to Bookies and ZKs, which already exists).
